TL;DR: In this paper, a digital image correlation (DIC) method is used to detect the process zone nucleation characteristics in granite, and a novel approach for representing AE data in terms of the inter-event time (IET) function F(τ) is employed to analyze fracture-related AE event rate characteristics.

TL;DR: In this paper, the authors present a number of models that explain how complex and overprinting structures can form by single-phase progressive deformation as strain accumulates in a deforming region.

TL;DR: In this paper, the authors use time-series displacement and length data from natural and experimental faults to elucidate growth styles and D-L trajectories throughout fault life, and assess the applicability of the two fault models.

TL;DR: In this article, the authors review the data constraining strain rates in the continents, and to consider the quantifiable range of crustal strain rates, where resolution allows, both spatial and temporal strain rate variations are explored.

TL;DR: In this paper, the authors applied the use of an Unmanned Aerial Vehicle (UAV) and the Aerial Structure from Motion digital photogrammetry image processing technique (ASfM) to study volcano-tectonics and tectonic features in an active Icelandic rift.

TL;DR: In this paper, the authors focus on the nature, relative timing, and multi-scale dimensional properties of both background and fault-related fracture networks that crosscut the Lower Cretaceous shallow-water carbonates exposed at the Monte Alpi, southern Italy.

TL;DR: In this article, the first regional balanced and restored sections across the northwestern part of the Zagros Fold-and-Thrust Belt in Kurdistan Region of Iraq and a 2D kinematic model that illustrates the evolution of the belt since Late Cretaceous time were presented.

TL;DR: In this article, the authors show that in some cases, these methods have been applied to samples that do not fulfill basic requirements, or developed on the basis of unsound conceptual models.

TL;DR: A range of applications to two-dimensional fracture and fault networks are discussed, and application to three-dimensions is briefly discussed.

TL;DR: In this article, the authors presented the results of detailed structural mapping on an exceptional, easily accessible 1-km long outcrop in the Neuquen Basin, Argentina, that exhibits a sill, its contacts and the structures in the finely layered sedimentary host rock.

TL;DR: In this article, the authors analyzed fault/fracture systems at the outcrop and map scale and define displacement thickness (D-T) scaling of fault damage zones using scanlines.

TL;DR: In this paper, the authors present the latest theories and observations about stylolites with respect to the key factors influencing the flow efficiency differentiation of these features, including their mechanical origin, their nucleation and growth, their past and present impact on reservoir properties and performances.

TL;DR: In this paper, McCaffrey, Paul Bons, and Sandy Cruden are thanked for their constructive reviews and the National Science Foundation grant EAR-1654518 is acknowledged.

TL;DR: In this paper, nearly 3,600 vertical joints were measured in sand-mud interbedded rock masses from 30 outcrops in the Yan'an area, China, and information such as joint spacing, joint aperture and the thickness of sandstone formations was obtained.

TL;DR: The authors showed that many structures form in "hydrogranular" or congested magma slurries during magma mush avalanching, local convection and late hypersolidus strain challenging the notion that magmas must have ≤55% crystals to convect/fractionate and form compositional diversity in upper crustal magma chambers.

TL;DR: Opposite shear sense (OSS) is manifested by the presence of conflicting shear senses in a portion of a rock body, a shear/fault zone or across several parallel shear or fault zones.

TL;DR: In this article, the authors describe fracture attributes and fault damage zones associated with a conjugate strike-slip fault system in tight Ordovician carbonate rock at depths of between 6500m and 7500m in the Tarim intracratonic basin in NW China.

TL;DR: In this article, the main chamber of the Lorette cave was modeled using high-resolution Structure-from-motion (SfM) photogrammetry and a 3D model of the cave was generated.

TL;DR: In this article, the authors study the active normal fault system that caused the Mw 6.3 2009 L'Aquila earthquake in central Italy, comparing the spatial distribution of coseismic offsets, cumulative offsets that have developed since 15'±'3 ka, and the total offsets accumulated since the faults initiated at 2'3'Ma.

TL;DR: In this article, the authors focus on field and laboratory analyses of carbonate fault cores pertaining to high-angle extensional fault zones currently exposed in the central and southern Apennines, Italy.

TL;DR: Scanlines across a range of fracture networks are analysed using cumulative frequency plots, spacing distribution and correlation integral plots, and a simple workflow is proposed that uses quantitative measures for the definition and characterisation of the spatial organisation of fractures.

TL;DR: In this article, a review of fracture-timing techniques for predicting fracture patterns and interpreting their mechanisms, including the role of fluid flow in early burial, is presented. But, the style and distribution of fractures vary dramatically based on fracture timing, highlighting the importance of constraining timing.

TL;DR: In this paper, a series of hydraulic fracturing physical simulation experiments were performed under true triaxial stress states and acoustic emission devices were used to monitor real-time hydraulic fracture propagation, which provided a reliable basis for optimizing hydraulic fracturing design in fractured-vuggy carbonate reservoirs.

TL;DR: In this paper, the deformation mechanisms and post-deformation diagenetic processes that affect deformation bands in carbonates are not so well understood, and the porosity and permeability of the resulting deformation band is investigated.

TL;DR: In this article, the authors used high quality 3D seismic reflection datasets from a selection of sedimentary basins to investigate fundamental characteristics of segmentation from the analysis of 67 normal faults with modest displacements.

TL;DR: In this article, structural, mineralogical and geochronological data were collected from two brittle fault zones (Fault I and II) deforming the Ordovician Rolvsnes granodiorite in SW Norway.

TL;DR: In this paper, fracture corridors are associated with strike-slip reactivation on sub-seismic faults in a context of polyphase deformation, and the relationship between folding and fracture corridor development in this area is indirect.

TL;DR: In this article, the authors used particle-image velocimetry (PIV) to define spatial and temporal variations in strain and vorticity in the sand layer during shortening.

TL;DR: In this paper, the orientation of the vorticity normal section (VNS) is determined independently from the finite strain fabric, and the orientation depends on the kinematics resulting from boundary conditions whereas the strain fabric orientation also depends on accumulated strain.

TL;DR: In this paper, a wide range of fault patterns associated with rift development in the Wichianburi Sub-Basin were identified, including influence by the margin of a Permian basin, and NW-SE to NE-SW trending Triassic folds and faults.
